Abstract:	A time-difference of arrival (TDOA) approach to locate active jammer source has been evaluated. The discussed monitoring system consists of several receivers distributed in space. In the proposed system time and frequency synchronization of monitoring receivers is implemented using GNSS observations. To achieve high accurate measurements both jammer and GNSS signals from all receivers are processed together simultaneously. Baseband processing block implements cross-correlation delay determination algorithm and calculates jammer position. This approach provides a possibility of determining a comparatively high accurate jammer location. Both computer simulation and experiments were used to test jammer monitoring system. The result of the study has shown that pseudorange-based jammer location technique can be implemented in practice.
